rated. Nevertheless, the periodic develo J ment of the streakings referred to, requires 19 more frequent redecoration than would otherwise be necessary if the entire ceiling area retained a uniform appearance.

Another object is to provide means that will accomplish the indicated objective without requiring any change in the present meth ods or accepted procedure now in vogue for construction of concrete floor and ceiling structures, having spaced beams of the character under consideration.

The foregoing and other objects are attained by the means described herein and disclosed in the accompanying drawing in which:

Fig. 1 is a perspective view, parts being broken away, of a concrete floor and ceiling structure and showing means embodying the invention.

Fig. 2 is a perspective view showing a fragment of a pan, forming a detail of the invention.

Fig. 3 is a perspective view showing a fragment of a lath, forming a detail of the invention.

In the construction of concrete floors and Q51 ceilings, it is common to provide the customary shoring 10, upon which is supported suitable stringers 11. Upon the stringers 11 are mounted suital le sofilts 12. In the particular disclosure in Fig. 1, the soflits 12 are spaced, for providing so-called open centering type of temporary flooring. If desired, the spaces between adjacent soilits 12 may he closed by suitable means for providing socailed solid decking. Upon the soliits 12 there are supported suitable laths 18 that may be of the character shown in Ma); S. Gold smith Patent 1,168,627. Suitable tiles, forms, or pans 14, may be received between the upturned ends 15, and 16 of the laths. or all purposes and intents the lath and the Serial No. 401,679.

forms may be identical with the laths and forms shown in the indicated Max S. Goldsmith patent, and as are also shown in my Patent 1,732,303. Between the upturned ends 15 and 16 of adjacent laths 13, there are provided tiller means for providing a chamber 17 above the sofi'its. The means disclosed herein for providing the indicated filler means comprise a pan 18 of inverted U-shape that is received within a lath member 19. The lath member 19 may be varied in shape and form. As shown herein, the lath 19 comprises a base 20, walls 21 and .22, and upwardly projecting and inwardly converging fianges 23 and 24c. The pan 18 is preferably of such size that it may be received within the lath member 20, thereby precluding the concrete that is formed over the filler means from entering into the chamber 17. The flanges 23 and :24- provided on the lath 19 are intended to lock the lath to the concrete of the beam 25 that is to be formed between adjoining pans or tiles 14.

It is to be understood that any means may be provided for providing a substantially continuous series of air spaces or empty chambers beneath the concrete ribs 25 and floor slabs 526, so that when plaster is applied to the under surface of the laths 13 and 19, the air chambers above the plaster will insure uniformity of condition throughout the area of the plaster, thereby obviating discoloration of one part of the plaster in relation to another part thereof and which now occurs in those instances where plaster is applied direct to concrete and in which structures there are provided spaced chambers between the concrete joists and beams.

Although the invention disclosed herein is exemplified in conjunction with structures such as shown in the aforesaid Goldsmith patents, it is to be understood that the invention is not to be confined to the specific types of structures shown in said Goldsmith patents. As illustrative of the use of this invention with other types of construction, attention is directed to the fact that the invention may be used with structures wherein the lath is secured to the forms or tiles and in which the tiles are held in the structure by the concrete, for example, as shown in my co-pending application Serial Number 87,661, filed February 11, 1926. Also it may be used in types of construction such as shown in the patent to Kuhne, No. 1,119,435, et cetera.

After the temporary flooring or soflits have been positioned and the various forms and laths have been positioned as shown in Fig. 1, concrete is poured over the forms for bonding the forms and the lath to the concrete. The resultant structure comprises a substantially continuous series of air pockets or empty chambers below all of the poured or formed concrete, and over all of which area plaster is then applied.

IVhat is claimed is:

1. In a concrete floor, the combination of lath, inverted U shape pans upon the lath, the pans being of different heights for providing rib molds over certain of the pans and between other of the pans, and concrete securing the lath and pans in a composite structure.

2. In a concrete floor, the combination of a continuous lath surface, rows of forms positioned over the lath, the forms of alternate rows being of substantially uniform heights, adjoining rows of pans being of different heights, whereby recesses are formed over the shallow forms and between the higher forms, all of the pans having upwardly extending supporting walls, the walls of adjacent pans being contiguous for substantially precluding concrete from flowing between and below adjacent pans, and concrete filling the recesses between the higher pans and securing the lath and pans into a composite structure.

3. In a concrete floor and ceiling structure the combination of spaced concrete ribs and means supported by the ribs for providing a rigid plaster receiving surface fixedly secured to the concrete and spaced throughout its horizontal area from and below the concrete ribs, the spacing of the plaster remiving means and its said surface providing asubstantially continuous air pocket between the plaster receiving face and the concrete.

4. In a concrete floor, the combination of rows of laths having upturned ends, the upturned portions of each row of laths abutting the upturned portions of adjacent laths, rows of pans between the upturned ends of each row of laths, each row of pans cooperating with its respective row of lath for providing a chamber closed at its top and sides, and concrete extending around the pans for securing the pans andlath in a composite structure, the chambers together providing an air pocket between and substantially coextensive with the lath and concrete.

5. In a concrete floor, the combination of rows of laths having upturned ends, the upturned portions of each row of laths abutting the upturned portions of adjacent laths,

rows of pans between the upturned ends of each row of laths, each row of pans cooperating with its respective row of lath for providing a chamber closed at its top and sides, succeeding rows of pans being of difierent altitudes, and concrete extending around the pans for securing the pans and lath in a composite structure.

6. In a concrete floor, the combination of rows of laths, having up-turned ends, a row of pans resting upon each row of laths between the upturned ends thereof, each row of pans cooperating with its respective row of lath for providing a chamber closed at its top and sides, and concrete covering the pans and joining the pans and lath the adjoining chambers providing an air pocket between the plastering surface and the concrete, such air pocket being substantially coextensive with. the floor.

7. In a concrete floor the combination of plaster receiving means, adjoining rows of inverted U-shaped pans upon the plaster receiving means, the pans of adjoining or succeeding rows being of different heights for providing rib molds over certain of the pans and between other of the pans, and concrete securing the plaster receiving means and pans in. a composite structure.

In testimony whereof, I have hereunto subscribed my name this 17th day of October,

\VILLIAM M. GOLDSMITH.
